Spool holder with 626 bearings for Elegoo Neptune 4

After creating the simple spool with sleeve and the spool holder with 608 bearings for my Neptune 4 I wanted to create one with bearings where reel will sit on top.

It is attached at the top of your Netpune 4 frame instead of original spool holder and can hold spools up to 64mm width.

You will need four 626 bearings (outer diameter -- 19mm, inner diameter -- 6mm, width -- 6mm).

Calibrate your printer (dimentions should be accurate as printed parts have to accomodate the ball bearings) and print:

• 1 Left body part;
• 1 Right body part;
• 4 Bearing pins;
• 2 Spools;
• 3 Bars;
• 1 Filament detector bracket.

Insert bars into body parts one by one and rotate 90 degrees using printed filament detector or pliers as a helper. Notice that bars should be rotated contra-clockwise if you look at them from the right. So when assembled, the bars flat surface should be at the front for the closest bar and on top fo other bars.

STEP file included.

I printed it on Elegoo Neptune 4 (0.4mm nozzle) in Jayo PETG with 0.2mm layer height, 0.6mm wall width, 25% gyroid infill, 3 walls, ~100mm speed without brim/supports.

Spool and bearing pins can be printed with brim for better adhesion.
